Thnaks, now rollback.c and rollback.h are both in the "source file list"!
Anyway I still have a problema with ddd: when I launch it I get the following
error message:
(gdb) tar extended-remote localhost:2222
Remote debugging using localhost:2222
0x00000000 in ?? () at
d:/cygwin/opt/ecos-gaisler/ecos-rep/packages/language/c/libc/stdio/current/src/common/ungetc.cxx:70
/opt/ecos-gaisler/ecos-rep/packages/language/c/libc/stdio/current/src/common/ungetc.cxx:70:2695:beg:0x0
(gdb)
No source file named d.
I can anyway link to my target and download the program. Anyway f =I try
openign a source I get the following errors: (exampls for sched.cxx and
rollback.c):
Line 1 of
"d:/cygwin/opt/ecos-gaisler/ecos-rep/packages/kernel/current/src/sched/sched.cxx" is

code.

(gdb)
No source file named d.
(gdb) list rollback.c:1
Line number 1 is out of range for
"d:/cygwin/opt/ecos-gaisler/ecos-rep/packages/tima_ft/current/src/rollback.c".
(gdb)
No source file named d.
(gdb)
Any Idea of the reason?
Thanks,

I still cannot use the functions I added in a new package: I will try
to be as clear as possible:
-- when building eCos my .c file is compiled
-- when I compile e progrma linking on ecos libraries everything is
fine too (I can call my functions)
-- when executing I get error
If I debug with DDD I notice that the function defined in my packages
are empty! Looking up the souirce list I can find the .h, but not the
.c!! I think that is the problem, I charge only the prototype and not
the real functions...But where I am wrong? The file is compiled? Maybe
something amiss in the cdl file?
Please someone help me, I cannto really go any further by myself!!!

Ps: here is the cdl file for my package:
cdl_package CYGPKG_TIMA_FT {
display "Tima funtionalities"
description " Blah blah blah 1"
# ====================================================================
# OPTIONS
cdl_component CYGPKG_TIMA_FT {
display "Blah blah 2"
flavor bool
compile rollback.c intr_rollback.S
default_value 1
requires CYGPKG_LIBC_SETJMP
description " Blah blah blah 2.1"
cdl_option CYGPKG_TIMA_FT_TRACE {
display "Enables Trace assertions"
default_value 0
description "
Blah blah 3"
}
}
}
And here how I call it up from ecos.db
package CYGPKG_TIMA_FT {
alias { "blah blah 0" tima_ft rollback }
directory tima_ft
script tima_ft.cdl
description "Blah blah 0.1"
}
Are your functions ending up in the final eCos application?
Do you have an applications that calls [at least one] directly?
If not, the linker may be throwing them out.
Try changing your "compile" directive to look like this:
compile -library=libextras.a rollback.c intr_rollback.S
Then
ecosconfig tree
make clean; make
Query: what's up with the "intr_rollback.S" file? eCos is designed
such that it's *very* rare to ever need to write anything in assembly.
